Associate Professor Akira Takatsuki's Conjecture, Vol. 1 (manga)

The mystical is nothing but phenomena plus interpretation, Fukamachi-kun. Naoya Fukamachi’s ability to unerringly detect lies has left him friendless and isolated all his life. It certainly isn’t helping him meet new people in college. But when he catches the interest of the handsome but eccentric associate professor of folklore studies, Akira Takatsuki, he finds himself with a part-time job- research assistant in charge of common sense, on a mission to help catalogue the supernatural!
